Compositing: Auto Lens flare from lighting.

edited January 2013 in Technical Questions and Answers #1
Ok what I am looking for is not a huge lensflars like JJ but those star flares and effects caused by in scene light.
I am looking for a plug or app that you take a image or rendering of the lights only and it generates the flares from tat with some adjustments for strength etc lenstype so on and what not. I was doing them in AE with the blurshift but it is just a PITA to set up every time. Probably some way of scripting the event but I am not a programmer. Or some other method in AE that I am unaware of. My major learning was way WAY back in the 90s so I barely get buy inside the app.

Anyhow back to the subject. I am looking for a plugin for AE premier PS whatever or app that will generate flares based on a image. I do not want anything like knoll where it is fake flares you have to manually place since they look so fake and well the way they do it setting a flare on point on a 8k image is impossible.

Does something like this exist? Is there a way to do this without craploads of set up? I have googled around looked at things and have not found any solutions except people pointing to multi hundred/thousand dollar solutions. or using these pregenerated or by the part kits that they place on each point of light.

This is for still work, least for now.

    I'm not sure if this is what you're after, but Video Copilot's Optical Flares has the ability to use luminance maps to generete flares, but they're dodgy as the point of luminance gets smaller...

    Yeah pretty close I hear it flickers on smaller crap but wouldn't matter for my current use. Costs is a bit much for what I will use it for too. Which is misc comps for the forum. Like to find a more shareware plug or something like than than a throw $$$ at it solution.

    Yea, I'm afraid I don't know of any other plugins... I emailed VCP and suggested they offer a demo version of some kind for Optical Flares... be it a time trial or feature limitation trial... but that was 2 years ago... lol.

    'convolve' is all you need, forget optical flares as it's just knoll with a few improvements

    IRML are you referring to the Genarts plugin...

    If it's the plugin, I'd get the trial (if it doesn't have any visual limitations) or rent it, "Convolve" from what I see, is part of an effects package, that starts at $1,699... if I read their website correctly...

    Sad part about KLF is in 3.0 they removed GPU acceleration, so it's sluggish...

    I do not know of any software but convolve is part of a mathematical filter system in many image apps. It is also a term used for sound shaping.
    Convolution is a mathematical operation that blends two functions relative to the overlap of one function as it is shifted over another.

    I have tried this with little success, likely some step I am missing or I am totally going in the wrong direction. Likely the latter.

    And yes if it is some expensive plug I am likely not able to use it. Connections for software are slim and work has been nonexistent. So even a 200$ plug is a bit un-doable right now.

    You might be able to use Trapcode Starglow...

    Looks sorta like the glare shader in max, wish I could just strip that out and use it as a filter on top of a image vs post. I do not think it applys to the backdrops or I would go that route though it cannot control elements separately.

    ATM I think I am stuck with what I am doing now. I just do not have the cash for pay for solutions and it seems that is the only thing out there atm.

    yes convolve is a mathematical operation, but there should be many different convolve plugins out there, I'm almost certain I've seen freebies in the past

    what you can then do is take the bokeh of the lens you are trying to duplicate, run a fourier transform on it in photoshop, and you get the diffraction flare for that bokeh, you use that as the matrix in the convolve plugin and it makes for some really nice and accurate glare

    also don't blend the glare layer using add, just use opacity, if your image is correctly HDR then an opacity around 1% should let the glare show but still leave the original image in the background
